Tillering structures the genotypic variability of wheat vegetative growth and its plasticity under water deficit.

Abstract excerpt

Whole plant leaf expansion (shoot expansion) under drought drives the tradeoff between water saving for later grain production and canopy photosynthesis. Fine-tuning shoot expansion could therefore become a target of genetic progress for drought-prone environments. However, its components (axis production [ie, tillering], leaf production on each axis, and individual leaf elongation) may have their own genotypic...
